  • Cohort 4: Refractory to platinum (i.e., relapsed ≤ 12 months after completion of chemotherapy) in the neoadjuvant/adjuvant setting.
  • Cohorts 4, 5, and 6: For individuals who received prior CPI, a treatment-free interval >12 months between the last treatment administration and the date of recurrence is required.

Additional Exclusion Criteria for Cohort 7:

  • Have had a prior anticancer therapy within 12 months prior to C1D1 or prior radiation therapy within 2 weeks prior to C1D1. Individuals participating in observational studies are eligible. Use of other investigational drugs (drugs not marketed for any indication) within 28 days or 5 half-lives (whichever is longer) of first dose of investigational product.
  • Have a history of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cohort 1: Sacituzumab Govitecan-hziy (SG)
Participants with urothelial cancer (UC) previously treated with platinum-based and/or checkpoint inhibitors (CPIs) will receive SG 10 mg/kg intravenously (IV) on Days 1 and 8 of a 21-day cycle.
Administered intravenously.
Other Names:
  • IMMU-132
  • Trodelvy™
Experimental: Cohort 2: SG
Participants with UC who are ineligible for platinum-based therapy and failed therapy with previous immune CPI therapy will receive SG 10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle.
Administered intravenously.
Other Names:
  • IMMU-132
  • Trodelvy™
Experimental: Cohort 3: SG + Pembrolizumab
Participants who have had progression or recurrence of UC following a platinum-containing regimen in the metastatic setting, or progression or recurrence of UC within 12 months of completion of platinum-based therapy as neoadjuvant or adjuvant therapy will receive SG 10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle and pembrolizumab at the standard approved dose (200 mg) only on Day 1 of a 21-day cycle. Lower doses of SG may be tested based on dose-limiting toxicities (DLTs) observed to determine the Recommended Phase 2 Dose (RP2D) of SG in combination with pembrolizumab.
Administered intravenously.
Other Names:
  • IMMU-132
  • Trodelvy™
Administered per package insert
Other Names:
  • KEYTRUDA®
Experimental: Cohort 4: SG + Cisplatin + Avelumab (Dose Escalation Phase)
Participants with UC who have never received therapy with platinum in the metastatic setting or for unresectable locally advanced disease will first receive cisplatin (either at 70 mg/m^2 on Day 1 of a 21-day cycle or at a split dose of 35 mg/m^2 on Days 1 and 8 of a 21-day cycle with a maximum body surface area of 2) and sacituzumab govitecan-hziy with maximum dose of 10 mg/kg intravenously on Days 1 and 8 of a 21-day cycle for up to 6 cycles. Based on DLTs observed, two additional lower doses may be tested to determine RP2D of sacituzumab govitecan-hziy in combination with cisplatin. If premature termination of 1 agent occurs due to toxicity, the other agent may be continued to complete up to 6 cycles of therapy. For participants who have not progressed, maintenance therapy will begin with infusions of avelumab 800 mg every 2 weeks beginning on Cycle 1, Day 1 and every 2 weeks thereafter and sacituzumab govitecan-hziy 10 mg/kg on Days 1 and 8 every 21 days.
Administered intravenously.
